Description
Elektromagnetisches Signalhorn mit Schneckentrichter Die Erfindung bezieht sich auf ein Signalhorn, insbesondere ein elektromagnetisches Signalhorn für Kraftfahrzeuge, das aus einer schwingungsfähigen Membran, angeregt z. B. über Anker, Elektromagneten und Spule, sowie einer Druckkammer vor der Membran und einem schneckenförmigen Trichter besteht, und betrifft die Ausbildung des Trichters.Electromagnetic horn with auger funnel The invention refers to a horn, specifically an electromagnetic horn for motor vehicles, which consists of a vibratory membrane, excited z. B. over Armature, electromagnet and coil, as well as a pressure chamber in front of the membrane and a helical funnel, and affects the formation of the funnel.
Bei den bekannten Signalhörnern, die zur Erhöhung der Abstrahlung vor einer schwingenden Membran einen Schalltrichter haben, weist der Schalltrichterquerschnitt seine geringste Stelle am übergang von der Druckkammer, die unmittelbar vor der Membran liegt, auf. Diese Anordnung bedingt eine ungünstige Lage des Trichters vor der Membran, d. h. in dein vor der Membranebene abgetrennten Halbraum auf der schallabstrahlenden Seite der Membran, und erfordert somit drei Einzelteile, nämlich das Gehäuse oder die Grundplatte zur Befestigung des Elektromagneten, die untere Trichterschale, die gleichzeitig die Druckkammer vor der Membran bildet, und die obere Trichterschale.With the known signal horns that increase the radiation have a horn in front of a vibrating diaphragm, the horn cross-section has its smallest point at the transition from the pressure chamber, which is immediately in front of the Membrane lies on. This arrangement causes the funnel to be in an unfavorable position the membrane, d. H. in your half-space separated in front of the membrane level on the sound-radiating Side of the membrane, and thus requires three items, namely the housing or the base plate for fastening the electromagnet, the lower funnel bowl, which at the same time forms the pressure chamber in front of the membrane, and the upper funnel shell.
Die Erfindung bezweckt eine günstigere Anordnung des Trichters und eine Vereinfachung des Aufbaus und erreicht dies dadurch, daß der Gehäusetopf, der die nicht schallabstrahlende Rückseite der Membran abdeckt, und der Gehduseabschlußdeckel, der zugleich die Druckkammer auf der schallabstrahlenden Vorderseite der Membran darstellt, gemeinsam den Schalltrichter bilden, derart, daß die Gehäusewand gleichzeitig als eine Trichterwand dient und die Radien der Trichterseele größer sind als der Membranradius, während die Ebene der Trichterseele hinter der Mem -branebene liegt.The invention aims at a more favorable arrangement of the funnel and a simplification of the structure and achieved this in that the housing pot, the covers the back of the membrane, which does not radiate sound, and the housing cover, which is also the pressure chamber on the sound-emitting front side of the membrane represents, together form the bell, such that the housing wall at the same time serves as a funnel wall and the radii of the funnel core are larger than that Membrane radius, while the level of the funnel soul lies behind the membrane level.
Diese Anordnung ergibt den Vorteil, daß Gehäuse und Schneckentrichter einteilig hergestellt werden können, während die verbleibende Öffnung lediglich durch einen Deckel abgedeckt wird, der zugleich die Druckkammer bildet.This arrangement has the advantage that the housing and the screw hopper can be made in one piece, while the remaining opening only is covered by a lid, which also forms the pressure chamber.
Die Zeichnung veranschaulicht ein AusführunIgsbeispiel der Erfindung an Hand eines elektromagnetischen Signalhornes, und zwar zeigt Fig. 1 die Draufsicht auf den Schneckentrichter und Fig. 2 einen Querschnitt durch das Signalhorn. Der Gehäusetopf 7 bildet gemeinsam mit dem Gehäuseabschlußdeckel 1 den Schneckentrichter 11, dessen Seele mit 8 gekennzeichnet ist. A ist der exzentrische Trichtereingang, r bedeutet den Membranradius und R den Radius der Trichterseele, wobei R größer ist als r. Die Druckkammer 2 ist aus dem Abschlußdeckel 1 ausgewölbt. Die Ebene 10-10 der Trichterseele 8 liegt hinter der Ebene 9-9 der Membran 3. Angeregt wird die Membran durch den Anker 4, die Membranspule 5 und den Magnetkern 6.The drawing illustrates an exemplary embodiment of the invention on the basis of an electromagnetic signal horn, namely Fig. 1 shows the plan view on the screw funnel and FIG. 2 shows a cross section through the horn. Of the Housing pot 7, together with housing cover 1, forms the screw hopper 11, the soul of which is marked with 8. A is the eccentric funnel entrance, r means the membrane radius and R the radius of the funnel core, where R is greater is as r. The pressure chamber 2 is bulged out of the end cover 1. The level 10-10 of the funnel core 8 lies behind the plane 9-9 of the membrane 3. Is excited the membrane through the armature 4, the membrane coil 5 and the magnetic core 6.
